ember.js - 如何从 Controller Action 内部获取父路由模型？

Question

在我下面的“约会” route ，我可以伸手获取父“日”的模型

App.Router.map(function(match) {                                          
    this.resource("day", { path: "/day/:day" }, function() {              
        this.resource("appointments", { path: "/appointments" }, function() {
            this.route("new", { path: "/:appointment_start/new" });
            this.route("edit", { path: "/:appointment_id/edit" });        
        });                                                               
    });                                                                   
});

但是，当我深入新路由或编辑路由时，我如何才能(从操作处理程序中)到达并像在路由中那样获取父“day”模型？

App.AppointmentsEditController = Ember.Controller.extend({                
    actions: {
        updateAppointment: function(appointment) {
            var day = this.get('??');
        }
    }
});

更新

最终的 Controller 代码现在看起来像这样

App.AppointmentsEditController = Ember.Controller.extend({       
    needs: 'day',         
    actions: {
        updateAppointment: function(appointment) {
            var day = this.get('controllers.day');
        }
    }
});

Toran - 很抱歉将其添加为额外答案，我还不能发表评论 - 是的，它应该是免费的。您可以访问 controllers.post从内部actions像这样阻止:

var postController = this.get('controllers.post')
